GreenRoc has completed processing tests on a representative 300 kg subsample of Amitsoq graphite ore. SGS Lakefield carried out 20 flotation tests followed by a locked-cycle test, producing a concentrate grading 95.2% graphite with more than 90% graphite recovery.

A locked-cycle test approximates continuous processing through a plant. Its results have provided a flowsheet for the next stage: processing Amitsoq’s full 20-tonne bulk sample at GTK Mintec in Finland. GreenRoc has signed an agreement with GTK, and the sample is being prepared for shipment.

The planned run is expected to produce several tonnes of graphite concentrate for GreenRoc’s active anode material pilot plant in Denmark. Processing results are expected before the end of 2026.

At Amitsoq, a survey identified three levels of historic mine workings. A scan of Level A and a partial scan of Level B are feeding a 3D model for mine planning and the planned Pre-Feasibility Study. After a September pause caused by limited helicopter availability, the team plans to resume the final two Phase III drill holes in the week of 5 October.

The SGS results now supply the process plan for a larger sample run, while the underground survey adds data for mine design. Both feed the next stage of Amitsoq’s development work.
